Geospatial Multistate Archive and Preservation Partnership (GeoMAPP)

A partnership with Library of Congress and state geospatial and archives staff.

Overview

The GeoMAPP effort aimed to address the preservation of “at risk” and temporally significant digital geospatial content. Geospatial data layers containing information about land parcels, zoning, roads, and jurisdictional boundaries change regularly. Existing copies of these data are often at risk of being overwritten when updates or changes are made and these superseded snapshots of data are then lost for future use and analysis.
